多价疫苗中每种血清型的有效抗原含量是影响疫苗质量的重要因素,以往检测技术存在无法分型和同时定量检测等问题。近日,中国科学院过程工程研究所生化工程国家重点实验室研究员张松平、苏志国团队利用毛细管区带电泳(Capillary Zone Electrophoresis,CZE)技术,实现了对O/A双价灭活口蹄疫病毒疫苗抗原(FMDV)中O型、A型完整病毒的同时定量检测,作为单价和双价FMDV疫苗质量控制...
日前,我所李典鹏研究团队基于广西壮族自治区八桂学者专项项目建设的高速逆流色谱平台,并在八桂学者Guido Frank Pauli教授及美国伊利诺伊大学芝加哥分校陈绍农博士的悉心指导下完成的研究论文“Preparation of flavone di-C-glycoside isomers from Jian-Gu Injection (Premna fulva Craib.) using recy...
We present a simplified method for simultaneous determinations of fluorine (F), chlorine (Cl), and sulfur (S) contents and isotopic abundances in rock samples. After using pyrohydrolysis to extract F...
In this study, recombinant histidine tagged p25 capsid protein of Maedi-Visna virus was developed. Part of the viral genome coding p25 protein was positioned downstream and in frame with a metal bindi...
日前,我所刘昭前教授及其研究团队在《Biomedical Chromatography》上发表一篇能同时检测5种CYP450酶的探针底物的相应代谢产物的液相色谱-质谱(LC-MS/MS)的检测方法。该方法能同时检测5种CYP450酶的探针底物的相应代谢产物:7-羟基香豆素,CYP2A6;4-羟基甲苯磺丁脲,CYP2C9;4-羟基美芬妥因,CYP2C19;α-羟基美托洛尔,CYP2D6;和1-羟基咪...
Different extraction methods, including extraction by organic solvents with and without acetic acid digestion,and mixed inorganic acid digestion coupled with solid phase extraction (SPE), were develop...
Surface derivatization of Kevlar, poly(p-phenylene terephthalamide), fiber has been studied along with the evaluation of the surface characteristics of the chemically-modified fiber as the stationary ...
Gas chromatography/resonance-enhanced multiphoton ionization/time-of-flight mass spectrometry (GC/REMPI-TOFMS) using an ultraviolet nanosecond laser was employed in the trace analysis of polycyclic ar...
The retention behavior on poly(oxyethylene) (POE) chemically-bonded stationary phases was investigated in ion-exchange, reversed-phase (RP) and hydrophilic interaction (HILIC) modes in capillary liqui...
A simple amperometric detection (AD) method based on mesoporous platinum (Pt) electrodes has been developed for the determination of sugars (glucose, fructose, and sucrose) with high-performance anion...
Capillary chromatography for the separation of optical isomers was developed using an untreated poly(tetrafluoroethylene) capillary tube and a water–hydrophilic/hydrophobic organic solvent mixture as ...
Novel packed-capillary columns for gas chromatography were developed with a thin-wall stainless-steel capillary of 1.0 mm i.d.; and rapid temperature-programmed separations have been carried out after...
A method was developed for fast and simultaneous determination of tetrafluoroborate (BF4−), thiocyanate (SCN−) and hexafluorophosphate (PF6−) by high-performance liquid chromatograph...
We have developed a capillary chromatography system using an open capillary tube made of fused-silica, polyethylene, or poly(tetrafluoroethylene), and a water–hydrophilic–hydrophobic organic mixture c...
In this study, a microemulsion electrokinetic chromatography (MEEKC) was used to analyze ten non-steroidal anti-inflammatory drugs (NSAIDs) in water samples. The type and ratio of organic modifiers we...
